I run an existing community with Discourse, the software that also drives this forum for Mattermost.
Discourse has its own SSO provider method
I would like a Mattermost plugin or integration that will let me limit account creation to Discourse users, and pull the username and perform authentication via the Discourse SSO provider API. I want to keep the entirety of user management in Discourse – I don’t want to have a second app with a separate set of users.
If you would like to do this work, please give me a quote as to how much you’ll charge for it in total.
